Description

RECOVERY - PER FAR 5.7 THIS NOTICE IS PROVIDED FOR INFORMATION PURPOSES ONLY; THEREFORE FAR 5.203 DOES NOT APPLY. THIS OPPORTUNITY WAS AVAILABLE ONLY TO CONTRACTOR(S) UNDER THE CURRENT CONTRACT NUMBER(S): MCMILLEN, LLC W91238-10-D-0001-CP0102 This contract action was accomplished using other than competitive procedures because this is an order under an existing contract that was awarded using non-competitive procedures. BACKGROUND: Warm Springs Dam, Lake Sonoma is located on Dry Creek, in Sonoma County, California 14 miles above the confluence with the Russian River and the City of Healdsburg. The San Francisco District (District) owns and operates two reservoirs on tributaries to the Russian River, Warm Springs Dam, Lake Sonoma in Sonoma County and Coyote Valley Dam, Lake Mendocino, on the EF Russian River in Mendocino County. Both dam are multi-purpose projects, consisting of flood control, water conservation and recreation facilities operated by the US Army Corps of Engineers, San Francisco District to reduce flood damages. Warm Spring Dam was completed in the early 1980s and consists of a rolled earth embankment, with a dam crest of 319 ft above the streambed. At gross pool, Lake Sonoma captures 381,000 acre-feet of runoff from the upper Dry Creek watershed, 130 square miles, above the Dam. Outlet flows are regulated via the projects two service gates and multi-level low flow outlet and an unregulated ogee spillway for emergency releases. The design flood peak inflow and outflow are 77,000 and 37,700 cubic feet per second, respectively, with 6 feet of freeboard. This study shall examine the adequacy of the Warm Spring Dam Spillway and its effects downstream of the dam, along Dry Creek and the Russian River. The study also includes a sunny day failure analysis. 3) OBLIGATION OF CONTRACTOR: The Contractor shall gather information, collect data, and perform analyses as necessary to successfully complete the tasks given in section 5 of this scope of work. All technical work performed as part of this scope of work shall be conducted by personnel trained in hydrology and hydraulics with a minimum of 3 years of experience. The work shall be supervised by a person trained in hydrology and hydraulics with a minimum of 10 years of experience who is also registered in the state of California as a civil engineer. 4) OBLIGATION OF THE GOVERNMENT: Government personnel will be available for advice, guidance, and comments on all work under this contract. Any comment, advice and/or guidance given by the Government personnel will be to assist the Contractor in performing the work and will not change the scope of work or release the Contractor from performing all work required herein unless written notification of such, signed by the Contracting Officer (CO) is received by the Contractor. Should the Contractor require assistance from the Government in regards to this scope, they shall contact one of the Government's points of contacts given in section 1 of this scope of work. The Government's point of contact will then either assist the Contractor directly, or provide an appropriate point of contact to answer the Contractor's questions. 5) DESCRIPTION OF WORK: The purpose of the study is to evaluate the adequacy of the Warm Spring Dam Spillway. The analysis shall determine the downstream inundation caused by both with and without failure analysis of the dam for the Probably Maximum Flood (PMF), as well as the 50-, 100-, 200-, and 500-year frequency based storms and a sunny day failure scenario. The District just completed a similar study for Coyote Valley Dam in July 2009; the same mythology shall be used in this study. This report shall be made available to the contractor prior to the Fee Proposal due date. The Coyote Valley Dam study routed the flood hydrographs from Coyote Valley Dam, thru the Russian River watershed (1400 square miles) to its terminus at the Pacific Ocean. The Russian River hydrology model developed for the Coyote Valley Dam study shall be used for this study, with modifications to the Dry Creek watershed (270 square miles). The Russian River hydrology model, as well as the flow data, precipitation data, GIS data, land use data, hydrologic models, and other data generated as part of the Coyote Valley Dam study shall be provided to the contractor for use in this study. Again, only the Dry Creek watershed shall require a detailed analysis, the existing Russian River hydrology model shall be used for the Russian River portion of the modeling effort. The hydrology model (HEC-HMS) will be calibrated and validated to the same historic data as the Coyote Valley Dam Study. Calibrated models will be used to model all of the events. The models will be run for with and without failure analysis of the dam for the 50-yr, 100-yr, 200-yr, 500-yr, and PMF events and a Sunny day failure scenario. Task 1. Data Needs and Analyses Vertical Datum: All work shall be conducted in NAVD88 vertical datum. This vertical datum shall be used throughout the analyses and report. Any data in any other vertical datum shall be converted to NAVD88. Most of the Districts documentation at Warm Spring Dam is reference to NGVD29, therefore converting to NAVD88 will be required for the study. Conversion data is available from a recent survey completed at Warm Spring Dam. This data shall be provided to the contractor. NOTE: Using NGVD29 benchmarks/elevations and converting them to NAVD88 using Vertcon is not acceptable. due to potential introduction of errors. If this is not possible, the contractor must identify another method for government approval before converting between NGVD and NAVD using Vertcon and/or other methods must be clearly documented. Accuracy of vertcon is about 2 cm RMS. For a study of this scope, the level of accuracy provided by vertcon is adequate. For hydraulic model data, MMC recommends computing a conversion value every 5 miles along the stream centerline. The closest conversion value to a particular element is then used to make the datum conversion for that element. A check of the accuracy provided by this method should be made to ensure the desired level of accuracy is being achieved. An alternate procedure for conversion of other data sets would be to follow an approach similar to that recommended by FEMA in Appendix B of Guidelines and Specifications for Flood Hazard Mapping Partners. The following modifications to the FEMA procedure are recommended. Locate subject jurisdiction (study area) by HUC boundary instead of county boundary (HUC boundaries down to the 12 unit code level are available at http://datagateway.nrcs.usda.gov). Compute conversion values on a 30 arcsecond grid instead of at USGS quad intersections. Use the largest HUC boundary for which the conversion criteria are met (criteria suggested by FEMA should be adequate for a study of this scope). Apply the average conversion to all elements within the HUC boundary. Horizontal Datum: All electronic data generated in this study shall be kept in a single consistent horizontal datum and metadata generated. A horizontal projection of USA Contiguous Albers Equal Area Conic USGS with units of US Foot shall be used. Both the vertical and horizontal units shall be in US Foot. Data Needs: The District shall provide all data that is readily available to the contractor and may include some of the following, data which the District can provide is noted in the below list. Where data is not readily available from the District, data will be acquired by the contractor from other sources. The contractor shall provide the District with a portable external hard drive to download all electronic data for the contractors use. Hydrologic Modeling: 1. Digital Elevation Models (10 meter DEMs) District to provide. 2. Soil coverages (STATSGO and/or SSURGO) - District to provide. 3. Land use data - District to provide. 4. Aerial photos - District to provide. 5. Base maps, USGS 7 minute quad - District to provide. 6. General GIS coverages, streams, watershed boundaries, roads, and so on 7. Point rainfall data for the largest 5 events of record, and latitude and longitude of each of the gages. District to provide (Russian River only, Dry Creek data will require a data search by the contractor). 8. USGS stream gage flow and stage data for the larges 5 events of record, all gages in around study area (5-60 minute time-series if available) District to provide (Russian River only, Dry Creek data will require a data search by the contractor). 9. Information for Warm Spring Dam, elevation-storage curves, outlet structures, spillways, and other physical information District to provide. 10. Historic antecedent reservoir stage data. 11. HEC-HMS model of the Russian River and supporting data District to provide. Data Analysis: Data analysis will consist of reviewing and organizing all of the data. The following tasks will be performed by the contractor: Hydrology Data: 1. Synthesis of existing study data 2. Gathering of stream network, watershed boundaries, and stream gage locations 3. Input point rainfall data into an HEC-DSS file 4. Quality check of all the precipitation and streamflow data Task 2. Development of the Hydrology Model The hydrology model developed for the Coyote Valley Dam Study, which encompasses the Russian River watershed from its headwaters to the Pacific Ocean, shall be used for this study and modified to develop the necessary details within the Dry Creek Watershed to accurately model Warm Springs Dam and it downstream contributions to the Russian River. The development of the hydrology model will consist of using HEC-GeoHMS to develop the basic data for HEC-HMS models. Then, the HEC-HMS models wills be calibrated using measured rainfall and stream flow data. Finally, the calibrated HEC-HMS models will be used to compute the runoff for the probable maximum flood (PMF) given the probable maximum precipitation (PMP), as well as the frequency based events. The PMP will be computed using guidance from HMR-58 and 59, Probable Maximum Precipitation for California. The frequency based storms will be based on NOAA Atlas 2 and TP-49 from the National Weather Service. Additional information will be gathered from the document called Short Duration Rainfall Frequency Relations for California, also from the National Weather Service. Rainfall frequency data for California is currently being updated by the National Weather Service, and will be part of the new NOAA Atlas 14, Volume V. All routings are to be done following normal authorized operating procedures found in the published water control manual. At a minimum the HEC-HMS model shall be calibrated to the February 1986, January 1995, January 2006 and January 1997 flood events and one other large event. The following is a detailed breakdown of the steps required to complete the work for the hydrologic modeling on Dry Creek: A. HEC-GeoHMS Modeling of Dry Creek Watershed 1. Data Processing - All geographic data collected and provided will be processed to have a common coordinate system and projection. 2. Significant Hydrologic Outlet Determination - Subbasin outlet locations will be determined for important hydrologic modeling locations, like stream gages, and in coordination with HEC-RAS model needs 3. HEC-GeoHMS Preliminary Run for Dry Creek Watershed - HEC-GeoHMS will be used to process the DEM data for preliminary watershed and stream delineation. Issues, shortcomings, and errors in the DEM will be uncovered and identified in terms of its ability to represent the terrain field conditions. Decisions will be made whether the DEM problems should be fixed. 4. DEM Editing of Dry Creek Watershed- DEM problems that significantly affect the watershed and stream delineation will be edited iteratively to better reflect the terrain field conditions. 5. HEC-GeoHMS Final Run - HEC-GeoHMS will be used to develop the hydrologic model with subbasin delineation at pre-determined outlet locations. HEC-GeoHMS will generate HEC-HMS project files, like the basin model file. B. HEC-HMS Model Development of the Dry Creek Watershed 1. Import HEC-GeoHMS files Files generated by HEC-GeoHMS will be imported into the existing Russian River HEC-HMS model. 2. HEC-HMS Parameter Estimation of the Dry Creek Watershed Model parameters for the subbasin loss, transform, and baseflow methods and for the river reach routing method will be estimated using available GIS data, gaged streamflow measurements, and regression equations developed from previous studies. 3. Update Russian River HEC-HMS model to accurately represent the Dry Creek contributions to the Russian River for this study. C. HMS Model Calibration/Validation 1. Development of Meteorologic Models Meteorologic models will be developed for historic storm events using rain gage, radar rainfall, or a combination of the two data types. 2. HEC-HMS Model Calibration - Models for historic events will be calibrated by adjusting hydrologic parameters. Events the model shall be calibrated to are, the February 1986, January 1995, January 1997, January 2006 and one additional historic event to be determined. 3. HEC-HMS Model Validate Models using the best parameter values from calibration will be used to model rainfall-runoff during a time window that was not used for model calibration. D. Development of the Probable Maximum Flood and Frequency based storms for Warm Springs Dam, Lake Sonoma. 1. Development of the PMP The PMP will be determined using HMR-58 and 59, and input into HEC-HMS. 2. Development of the PMF Model parameters from the calibration/validation process will be used along with the PMP to compute the PMF. 3. Frequency based storms will be developed from NOAA Atlas 2 and TP-49 from the National Weather Service, with additional information from Short Duration Rainfall Frequency Relations for California, also from the National Weather Service. 4. Frequency based storm data will be input into HEC-HMS using the Hypothetical storm option in the model. 5. Model parameters from the calibration/validation process will be used along with the frequency based rainfall data to compute the runoff for the frequency based storm events. 6. The starting pool level for the PMF shall be determined as required by ER 1110-8-2 (FR). The District shall decide which starting pool level shall be used for the PMF routing based on the following analyses: i. Starting pool level at the spillway crest elevation (495 NGVD). ii. Starting pool level will be the pool level prevailing after routing an antecedent event occurring five days after the last significant rainfall form a hypothetical storm the produces one-half the PMF as determined by the Contractor. 1. A sensitivity analysis shall be conducted to determine the starting pool level, particularly if the initial pool level is below the spillway crest elevation. 2. The contractor shall gather historic antecedent reservoir stage records occurring before the maximum 72-hr precipitation period of major storm event for this task. 7. Reservoir releases shall be evaluated with a maximum release through the service gates at 6,000cfs and 7,900cfs and assess the effect on the pool level during the PMF. (The gates are designed to release a maximum flow of 7,900cfs, however, a flow of this magnitude may not be safe due to the installation of a 20-inch diameter emergency water supply line to the fish hatchery that hangs from the ceiling of the outlet tunnel.) Task 3. Field Trip/Meetings Several field trips to view the river system/watershed and collect data are required of the contractor. It is anticipated that three (3) staff member for two days in the field would be sufficient to visit the project site and Dry Creek downstream and for and over view of the Russian River. Additionally, the kick off meeting would be used to meet with District personnel. The purpose of meeting would be to discuss the project status/problems and collect additional information. Task 4. Project Management and Coordination The Contractor will use appropriate project management practices to ensure that quality submittals are delivered on time and within budget for this scope of work. To ensure a quality product, the Contractor will confirm that their quality control procedures meet Corps standards. The Contractor should be prepared to discuss the status, important results to date, and any issues of concern for the project. Also note that the Contractor should contact the H&H Tech Rep immediately with any issues of major concern for the project. The contractor shall be prepared to meet with the H&H Tech Rep three (3) times at the Corps offices.
